In yet another twist in the Aarushi-Hemraj double murder case, Hemraj's wife has moved the Supreme Court, challenging the Allahabad high court's decision to acquit Dr Rajesh and Nupur Talwar. Earlier in October, the Allahabad high court had exonerated jailed dentist couple Rajesh and Nupur Talwar of the charges of killing their daughter Aarushi and domestic help Hemraj, citing a lack of clinching evidence and the possibility that an outsider could have committed the crimes.
